A method for investigating the stomach using spiral CT was developed a
nd 15 patients with normal stomachs were examined. The anatomy and wal
l thickness was studied. The method was tested in the preoperative sta
ging of 35 patients with a high suspicion of gastric cancer. Compariso
n of the CT results with endoscopic, radiographic, surgical and histol
ogical findings showed that in advanced gastric cancer the full extent
of the disease is better visualised with CT than with conventional me
thods. There exists, however, a problem of false-negatives regarding l
ymph node involvement.
